How to retrieve a CD's barcode?



there’s a number of drives which can apparently read the bar code printed on commercial CDs. I happen to own one of those, the MATSHITA DVD-RAM UJ-850S, but I’m puzzled about how to actually get the drive to read it.

I searched the web for some time, but I couldn’t even find anything remotely related to my question… just basic bar code information, or test results for drive’s features. Are there any tools or means out there to read the bar code with this drive from my laptop?



Check out this document and look at page 420 and the following ones (in the document 420 is numbered as 372). There you can see which command is required to retrieve the barcode and how you can verify that the drive actually provided a valid barcode.

You can use tools like fPLSCSI to communicate with a drive.
